Abstract: Apparatus (10) for treating a waterway having low pH and containing metals such as aluminium in solution, as a result of runoff from acid sulphate soils, is capable of dosing the waterway with a variety of reagents, to bring the metals out of solution and to achieve a neutral pH. The apparatus (10) includes a rotating drum tumbler (14) having a cylindrical drum (52) which, as it rotates, causes limestone rock to abrade to produce particles of calcium carbonate with which the waterway may be dosed. The inner surface of the drum (52) is provided with an abrasive surface (68) which contacts rock pieces (74) and transports them within the drum (52) as the drum (52) rotates, and with guide vanes (72) which contact and deflect the rock pieces (74), causing the rock pieces (74) to abrade each other. Other reagents in liquid and/or powder form may also be dispensed.

Title: Nut feeding method and nut feeder
Inventor: SAKOTA KOUJI
IPC: B23P19/06
Filed: 2007-10-17
Granted: 2012-04-24
Abstract: A small-diameter front-end portion of a feed rod is allowed to enter into the screw hole of a nut delivered by a nut chute, and the nut is fed to an intended position by the forward movement of the feed rod. When an abnormal nut having a screw hole into which the small-diameter front-end portion cannot be inserted is delivered, the abnormal nut is prevented from being flicked by the feed rod. In order to achieve this, in a standby state, the small-diameter front-end portion of the feed rod enters a nut receiving chamber and is then stopped. On condition that the abnormal nut is received in the nut receiving chamber, if the feed rod moves forward to enter into the standby state, the abnormal nut is slightly pushed out forward from the nut receiving chamber.
